When you send an e-mail with Windows Live Hotmail, you can attach pictures and other files to your message.
Sign in to the Windows Live Hotmail website with your Windows Live ID (The user name and password that you use to sign in to any Windows Live, MSN, or Office Live sites and services. If you have a Passport Network, Hotmail, or Messenger account, you can use it as your Windows Live ID.) .
In the left pane, click Mail, and then, in the upper-left corner, click New.
Click Attach, and then click File.
Locate and select the file that you want to attach, and then click Open. Repeat this step for each file that you want to add.
Notes
To remove an attached file, next to the file name in the message header, click Remove.
If you've chosen to save a copy of your sent messages, a copy of the attachment is saved as well.
Any file that you attach to an outgoing message is automatically scanned by Trend Micro antivirus software. If a file contains a virus, you won't be able to attach it to a message.
Some e-mail programs, such as Microsoft Outlook, can block certain types of attached files to help protect against viruses. You'll be notified if you attach a file that others may not be able to open.
For a free Windows Live Hotmail account, the maximum size for an attachment is 10 MB.
